Hardware reality: sufficient for now - back to C!

[sorcerer_see]

As you could read in my former posts I temporarily halted my C course because I had some fundamental hardware questions popping up, which needed to be cleared up so that I more or less know what I am doing to the machine while programming. Thus I have been reading a lot , watching a lot of educational videos, and then I have been trying to formulate a few definitions here in my blog of what I understand now about how the machine, under the programming, works. It was not my intention to understand the topic in detail because the question then arises: how far to go with this...

Knowing everything about IT is in any case impossible, the subject became too large for that.

I feel I know enough now to continue with C. My goal is C mastery. For being a good high-level programmer I need some feeling with the machine, but without having to be a technician. The main focus is C.
